Climate Chart of Aspen Snowmass, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures reach their highest point in July at 17.1 °C, while the coolest monthly mean is in December at -6.8 °C. These are monthly averages, not daytime highs or lows, so they describe the broad temperature character of each month rather than the range visitors may experience from day to day. Across the calendar-month means, the unweighted average temperature is 4.0 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall is highest in July at 1.24 mm/day, and lowest in both January / December at 0.01 mm/day. These are daily average amounts rather than monthly totals, and a low mean does not show how often rain occurs or guarantee dry weather. The unweighted average of the monthly mean daily rainfall figures is 0.52 mm/day; this summary should not be read as the amount falling in a typical day or as a monthly accumulation.

Sunshine

Mean daily sunshine duration peaks in June at 13.39 hours/day and is lowest in December at 6.51 hours/day. These figures describe average sunshine hours, not day length, and do not establish how clear any particular day will be.

Snow

Snowfall is also represented as a daily mean: it is highest in December at 17.04 mm/day. The unweighted average across the monthly mean daily snowfall figures is 8.90 mm/day, not a monthly total.

Best Travel Time Guide for Aspen Snowmass, USA: Ideal Seasons and Weather Insights

If you prioritise cooler monthly averages, December is the relevant option, with a monthly mean temperature of -6.8 °C; this does not indicate daytime temperatures or the conditions on your specific travel dates. For lower average rainfall, consider January / December, when mean daily rainfall is 0.01 mm/day. That average cannot guarantee rain-free days or tell you how frequently rain occurs, so flexible plans and weather-ready clothing remain sensible. For rain preparation, July has the highest mean daily rainfall at 1.24 mm/day, making rain protection worth considering for outdoor sightseeing. Visitors planning around sunshine can note that mean daily sunshine reaches 13.39 hours/day in June, compared with 6.51 hours/day in December; sunshine duration is not day length and cannot promise clear skies. These averages offer planning context, not a forecast for a particular visit.
